Abstract

Under a technology based on the generalized mean of inputs and outputs with constant returns to scale (CRS), the firms have incentive to merge (in a firm game) in order to improve their technical efficiency. A directional complementarity property in inputs and in outputs is introduced. It is shown that the core of the firm game is non-void whenever the aggregate technology of each coalition exhibits complementarity in outputs and CRS. In the case of $$\alpha $$ α -returns to scale, the firms have incentive to merge (improvement of technical efficiency) when there are both directional complementarity in inputs and in outputs.
